10 is fitted between the outer ring 60 and the inner ring 70, and is an outer cage.
A sprag 40 as a torque transmission medium held between the inner retainer 20 and the inner retainer 30 is in contact with the inner and outer races. 50 is a drag clip for fixing the outer cage to the outer ring. In the illustrated example, when the outer ring rotates in the clockwise A direction or the inner ring rotates in the counterclockwise a direction, they both idle and do not transmit torque,
Conversely, the outer ring is counterclockwise in the B direction or the inner ring is in the clockwise b direction.
When rotated in the direction, the sprag 40 stands up, frictional engagement occurs between the inner and outer rings, and torque is transmitted to the other party.

とは同様である。1 to 3 show steps of manufacturing the cage according to the present invention. A metal plate is drawn to form a bowl-shaped body 20 '(FIG. 1), and then the bottom plate 25 is B'by punching. Punching is carried out at the position indicated by to form the cage 20 as shown in FIG. Further, as shown in FIG. 3, the sprag holding holes 24, ... Are punched to complete the process. In the same figure, 21 is a diaphragm surface and 22 is a collar portion.

止になる。Since the cage according to the present invention has the rounded radius R on the outer peripheral corners as described above, it is easy to assemble the drag clip. That is, as can be seen from FIG. 9 and FIG. 10 which is an enlarged view of the lower portion thereof, the upper piece 51 ′ of the hanger 51 and the root portion 52 are R-shaped.
Since the step 26 is brought into close contact with the portion 26, the step of the drag strip can be prevented, so that the inclination of the drag strip can be prevented. Further, if the lower piece 51 ″ of the hanger is fitted to the slope of the punched surface 25, the inclination can be further prevented.
さらに第11図に示す如く外輪への挿入のとき、挿入方
